摘要： The disclosure relates to methods and devices for performing uplink power control in a radio communication system. An example method comprises a step of receiving, at a user equipment (UE) a transmit power control (TPC) command. The method also comprises, if the UE does not have an uplink transmission scheduled for a subframe associated with the TPC command, a step of accumulating, by the UE, the TPC command with previously received TPC commands based on whether the UE has reached a maximum transmit power or a minimum transmit power in a reference format for a Physical Uplink Shared Channel (PUSCH), Sounding Reference Signal (SRS) or Physical Uplink Control Channel (PUCCH) transmission. Thus the UE is enabled to receive TPC commands while the UE is not transmitting anything in the uplink.
摘要翻译：本公开涉及用于在无线电通信系统中执行上行链路功率控制的方法和装置。一种示例性方法包括在用户设备（UE）处接收发射功率控制（TPC）命令的步骤。该方法还包括：如果UE没有针对与TPC命令相关联的子帧进行调度的上行链路传输，则UE基于UE是否达到最大值，先前接收到的TPC命令累积TPC命令的步骤用于物理上行链路共享信道（PUSCH），探测参考信号（SRS）或物理上行链路控制信道（PUCCH）传输的参考格式的发射功率或最小发射功率。因此，当UE不在上行链路中传输任何内容时，UE能够接收TPC命令。

摘要： The invention concerns a method of managing coexisting packet streams (100, 110) in a wireless communication system, and a corresponding controller and a mobile terminal. A first packet stream (110) of the coexisting packet streams (100, 110) requires transmission resources of the wireless communication system at fixed time intervals, and a second packet stream (100) of the coexisting packet streams (100, 110) requires transmission resources of the wireless communication system at dynamically determined time intervals. A schedule defining allocations of transmission resources for the first packet stream (110) is set up. A request for an initial grant of transmission resources for a transmission of a data packet (101) of the second packet stream (100) is issued. In the process of allocating transmission resources to the second packet stream (100), the controller analyses the schedule of transmission resources allocated to the first packet stream (110) and thereby determines whether a retransmission (102, 103) of the data packet (101) associated with the second packet stream (100) is possible to collide with a transmission of a data packet (111, 112) associated with the first packet stream (110) according to the schedule. The controller transmits a parameter specifying a number N of retransmissions (102, 103) possible without such collision as part of the initial grant of transmission resources to the mobile terminal.

摘要： A method is provided for maintaining synchronization between an AT and a base station during an idle period. During the idle period, a reduced number of uplink reference signals for uplink channel quality estimation are sent to the base station by the AT. The uplink reference signals are sent to assist coherent demodulation and uplink channel quality estimation for scheduling. During the uplink idle period, the numbers of uplink reference signals are designed to be reduced in selective coherent bandwidths. The selection of the coherent bandwidth alternates in time and covers the entire spectrum to allow the channel quality estimation through the entire spectrum.

摘要： A technique for controlling a receiver to enter a micro sleep mode during which at least one receiver component is temporarily switched off is described. The receiver is configured to process sub-frames each having a first sub-frame portion followed by a second sub-frame portion, the first sub-frame portion carrying information indicative of whether or not the second sub-frame portion needs to be decoded. A method implementation of this technique comprises the steps of providing a regular micro sleep mode in which the receiver component is switched off after the first sub-frame portion has been decoded in case the decoding indicates that the second sub-frame portion does not need to be decoded, providing an extended micro sleep mode in which the receiver component is switched off immediately after the first sub-frame portion has been received, evaluating a mode setting criterion, and controlling the receiver to enter the regular micro sleep mode or the extended micro sleep mode depending on the mode setting criterion.
